Byte * 8 + Bit for NumBLs. NumBLs is informative. Not for LAD/FBD. call of a user block. Not in Graph ActionList. call of an instruction. Not for LAD/FBD, Graph ActionList. STL specific Only in SCL SCL specific for absolute addresses Not allowed in STL for DB access In general it is Byte * 8 + Bit. But if it is used for addressing a DB we will find the number of the DB here (e.g. "DB12" ->12). if true, the import unnoted it partly qualified access with DB register partly qualified access with DI register Classic Local Stack Not for LAD/FBD. for BlockNumber. BlockNumber is informative. for ParameterModifiedTS. ParameterModifiedTS is informative SCL SCL For the indices of an array If component has child AccessModifier is Array else AccessModifier is None for Format and FormatFlags. They are informative.. the DOT; only if separated. Not in Graph ActionList, not in LAD/FBD. Not allowed in STL SCL only for InterfaceFlags. InterfaceFlags is informative The type of the value should be InterfaceFlags_TP The default value is "S7_Visible" for NumBLs. NumBLs is informative for InterfaceFlags. InterfaceFlags is informative The type of the value should be InterfaceFlags_TP The default value is "S7_Visible" SCL SCL Symbols we do not know what they are Only for S7-300/400/WinAC SCL. Not allowed in STL
